Polycentric binding in complexes of trimethylamine--oxide with dihalogens.

Dihalogens readily interact with trimethylamine--oxide under ambient conditions. Accordingly, herein, stable 1 : 1 adducts were obtained in the case of iodine chloride and iodine bromide. The crystal and molecular structure of the trimethylamine--oxide-iodine chloride adduct was solved.
